Chapter 7.10, Problem 7.31P

Interpretation Introduction

Interpretation:

The final temperature of the mercury and the copper is to be determined at $15°\text{C}$ when 20cal of heat is added to the 10g of each copper and mercury.

Concept introduction:

The specific heat can be calculated as follows:

  $\text{specific heat=}\frac{\text{Heat}}{\text{Mass×ΔT}}\text{=}\frac{\text{cal or J}}{\text{g}\text{.°C}}$

Also,

  $Q=m\times C\times \Delta T$

Or,

  $\Delta T=\frac{Q}{m\times C}$

Here,

Q = amount of energy or heat added

m = mass

C = specific heat

  $\Delta T$ = change in temperature
